The 2026 Drupal Business Survey is open. Your response will help shape the future of the Drupal business ecosystem.I am having some serious trouble with thumbnails when I have high resolution pictures (hopefully I am using the proper terminology; the pictures X by Y measurements). I orginally did not have a limit on the resolution of images that could be uploaded and it just slowed the site down way too much. The resolution I am using is 3888 x 2592 (10.1 megapixel). I also noticed during this time that thumbnails were not being created for certain issues. I decided to limit the resolution uploaded to 1080p (1920 x 1080); while the actual images load much faster, I am still having a great deal of trouble with the thumbnails not displaying. I have tried flushing the imachecash, but no success there. You can check it out here:

You will notice the first gallery does not have any problems (1280 x 863 pictures), whereas the second gallery does have problems (3888 x 2592, which have been scaled down by ImageTool to the limitations I put in at 1920 x 1080).
Thoughts?

dbeall commentedThis looks to be an imagecache and/or server issue.
I just don't see where views or node gallery could be the trouble.
The images are being uploaded, which is node_gallery, ImageAPI and the file system at work.
After the files system gets the files, the covers and thumbnails are produced by imagecache, if they are not generated, node_gallery can't display them.
The problem seems to be the creation of the thumbnails with imagecache.
I have done some looking around in the imagecache issues and there are some problems with ultra-high resolution images. Some people pointed at the php.ini settings for file size, processing time limit and some even talked about htaccess.. I am thinking it's more of a php file size or timeout issue.
access the full image,, it shows up, is in the file system.(node gallery working)

access the thumbnail,, error, or not there, imagecache did not create the thumbnail.(imagecache not working) -or- (server can't handle the request)

I would try setting the upload fields to one image upload at a time when using such a high resolution.
-Or-
Upload one image at a time, leaving the rest of the upload fields empty.
This will give the server half a chance at handling the ultra-high resolution image processing requests.
edit: you could also try setting the image re-size size limits to something more reasonable, like 800x600 or 600x400

frank0051 commentedHmm, it seems like when the file is below 3 megs and the total is no more than 5 megs it can generate the thumb. Little strange; I don't think it is PHP because the images make it onto the server, just the thumbs aren't generated. It might have something to do with GD.

frank0051 commentedI switched ImageAPI over to ImageMagicK; it is iffy, but there have been some successes in generating the thumbnails (unlike GD2).

justintime commentedProbably a PHP memory limit. Have you checked yr Apache error logs?
Comment #5
kmontyThis is an imagecache request. I would also recommend editing your php mem limit and/or setting a maximum upload size.

atul_shin commentedI am facing issue with imagecache but quite different.
I am using "node_gallery" module for gallery display. This module creates three presets by default, for thumbnail, display and cover image. I am displaying images by a custom module. When I create a gallery through "node_gallery" module and upload images for first gallery images thumbnail and display images are created but when I create a gallery second time thumbnails are created but other images relating to display presets are not created again.
I tried all the things related to imagecache discussed here but no results...
please any help
