pictures without extension in admin panel

[Motive]

I am on oscMax 2.025.
I have just installed this and have been setting it up.
I used easy populate to load my products and image references. And then used FTP to load my big images and thumbs to their respective folders.
Today I am looking through my admin section (renamed) and I found 32 files without extensions following this naming pattern "pThumbfG4UUn". I downloaded one and put jpg extension on it and it is an image of my product.

Question is where did they come from and why?

This is a known 'issue'.
Remove (delete) them all, then change permissions of your admin directory to to read-only eg. 555
It's caused by the caching of thumbnails during the image resize feature in the product admin. This is addressed in SVN r674 (Developers section above).

catalog/ admin/ includes/ functions/ instant_update.php

Line 12

  $cache_dir = 'cache/';

Line 51

                        $phpThumb->setParameter('config_cache_directory', $cache_dir);

Line 89

                        $phpThumb->setParameter('config_cache_directory', $cache_dir);

Note your version may not have the same line numbers above and only one copy of the $phpThumb->setParameter directive. Take a backup of the file and alter the code so that it appears the same as above.

The one advantage of installing from the latest SVN - you get bug fixes and feature enhancements already installed.

ya so I only have one instance of

$phpThumb->setParameter('config_cache_directory', $cache_dir); 

and that is on line 51. Commented next to it was "this doesn't work"
I added the line to 12. I only go up to Line 81. So this is what I ended up with

<?php
  $images_dir = DIR_WS_IMAGES; // default catalog images folder;
  $exclude_folders = array("banners","default","icons","mail","infobox","js"); // folders to exclude from adding new images
  $root_images_dir = DIR_FS_CATALOG .  $images_dir . DYNAMIC_MOPICS_BIGIMAGES_DIR;
  $root_thumbs = DIR_FS_CATALOG . $images_dir . DYNAMIC_MOPICS_THUMBS_DIR;
  $html_images_dir =  DIR_WS_CATALOG .  $images_dir . DYNAMIC_MOPICS_BIGIMAGES_DIR;
  $html_thumbs =  DIR_WS_CATALOG .  $images_dir . DYNAMIC_MOPICS_THUMBS_DIR;  
  $new_dir = preg_replace('/[^a-zA-Z0-9_.-]/i', '_',$_POST['new_directory']); 
  $dir = (tep_not_null($new_dir) ? $new_dir : $_POST['directory']);
 
// instant update 
   if ($action == 'new_product_preview') {
    $cache_dir = 'cache/';  //added this to solve a cached thumbnail problem
 
// copy image only if modified
        if ($dir && !is_dir($root_images_dir . $dir)) { 
       if (mkdir($root_images_dir . $dir)) $messageStack->add('Folder ' . $dir . ' created in '. $root_images_dir . '.', 'success');
    }
        if ($dir && !is_dir($root_thumbs . $dir)) { 
       if (mkdir($root_thumbs . $dir)) $messageStack->add('Folder ' . $dir . ' created in '. $root_thumbs . '.', 'success');
    }    
        $products_image = new upload('products_image');
        $products_image->set_destination($root_images_dir . ($dir ? $dir .'/' : ''));
 
        if ($products_image->parse() && $products_image->save()) {
          $products_image_name =  ($dir ? $dir . '/' : '') . $products_image->filename;
require_once( DIR_FS_CATALOG . 'ext/phpthumb/phpthumb.class.php');
// create phpThumb object
$phpThumb = new phpThumb();
// create 2 sizes of 'thumbnail'
// Note: thumbnail referenced below applies to both image sizes.
$thumbnails = array(PRODUCT_IMAGE_WIDTH => $root_thumbs, POPUP_IMAGE_WIDTH => $root_images_dir);
foreach ($thumbnails as $thumbnail_width => $dest_dir) {
 // this is very important when using a single object to process multiple images
 $phpThumb->resetObject();
// set data source -- do this first, any settings must be made AFTER this call
if (is_uploaded_file(@$_FILES['userfile']['tmp_name'])) {
 $phpThumb->setSourceFilename($_FILES['userfile']['tmp_name']);
  $output_filename = $dest_dir . $dir .basename($_FILES['userfile']['name']).'_'.$thumbnail_width.'.'.$phpThumb->config_output_format;
} else {
 $phpThumb->setSourceData(file_get_contents($root_images_dir . $products_image_name));
 $output_filename = $dest_dir . $products_image_name;
}
// set parameters (see "URL Parameters" in phpthumb.readme.txt)
$phpThumb->setParameter('config_cache_directory', $cache_dir); //took out "DIR_FS_CATALOG . 'cache/'" and replaced with $cache_dir to fix a thumbnail cache problem
$phpThumb->setParameter('w', $thumbnail_width);
if ($dest_dir = $root_images_dir) { 
 $phpThumb->setParameter('h', POPUP_IMAGE_HEIGHT);  //specify max height for popup
 $phpThumb->setParameter('q', 90);  //maintain higher quality for popup
 }
// generate & output thumbnail
if ($phpThumb->GenerateThumbnail()) { // this line is VERY important, do not remove it!
 if ($phpThumb->RenderToFile($output_filename)) {
  // do something on success
 } else {
  // do something with debug/error messages
  echo 'Failed:<pre>'.implode("nn", $phpThumb->debugmessages).'</pre>';
 }
} else {
 // do something with debug/error messages
 echo 'Failed:<pre>'.$phpThumb->fatalerror."nn".implode("nn", $phpThumb->debugmessages).'</pre>';
}
}
// end thumbnail creation                
        } else {
          $products_image_name = (isset($HTTP_POST_VARS['products_previous_image']) ? $HTTP_POST_VARS['products_previous_image'] : '');
        }
 if ($_POST['instant_update'] == 'on') { 
   $_POST['products_image'] = stripslashes($products_image_name);
        $action = (isset($_GET['pID']) ? 'update_product' : 'insert_product');  
 }
}
?>

Now once this is done can I change my admin back to 755 or should I leave it at 555?

After I posted this I was looking at r674. should I delete everything that is in red?

[ridexbuilder]

Move

$cache_dir = 'cache/'; 

to below

$dir = (tep_not_null($new_dir) ? $new_dir : $_POST['directory']);

(Keeps it closer to the corrected file, if you look at the SVN.)
Keep the admin directory at 555 ('safer' anyway)
You may need to create public_html/cache and or catalog/youradmin/cache, depending on your server environment.

Given that you're a relative newbie, that may get too complex.
(You need to add as well as remove.)

"this doesn't work"

My comment, BTW.

[ridexbuilder]

Additional note for the curious...
This file may get another makeover (if I can be bothered), to take advantage of the new image generator feature in 2.1
It will considerably clean up the file and make is a lot simpler to follow - don't hold yer breath.

I've never had a problem using the delete key before.
