I'm have a strange problem in that when images are uploaded, they are not consistently creating thumbnails. Some are, some are not. I only am specifying for 1 thumb to be created. I don't even see the thumb in the uploads/thumb folder.

Why would some work, but not others?
My thumb size is 300 x 300 px, and the images I'm uploading are 500 x 312 or so, so that shouldn't matter.

I have version 1.22 of CMS Builder.

The images I'm uploading are jpgs.

Also, if I click on the button to recreate the thumbnails, I get this error:

Error: SaveResampledImageAs: Unknown image type

I think that may be the root of the problem, but I don't know what it means. My files have .jpg extensions, and that is a valid upload type...

Hi Dave, I see you answering questions all around my post, PICK ME!

I would buy into priority support, but it's the weekend, so that won't help me until Monday. :(

Hey, Cap -

Just to help fill out the picture...

When you upload your image do you see a copy of it in the preview window?

Yes, it shows up in the preview, and in the uploads directory.

I even tried manually creating a thumnail and putting it in the thumbnail directory, hoping it would pick up on that, but it didn't.

Is it possible it's just something awry with those files? Most images have worked fine.

That's certainly a possibility. If it's always the same images that fail then I suspect they could be at the heart of the problem?

Recently, one of my clients had difficulty uploading some images on to X-cart. She tried everything - without success. In desperation she sent the files to me and even I couldn't get them to upload. In the end I opened the pictures in Photoshop and simply re-saved/exported them. The next time I tried to upload them everything worked as normal.

In such circumstances it's worth trying everything - even if it's not the most obvious solution!

PS. Incidentally, and for the record, the client in question works exclusively on a Mac. I work solely on Windows!

I had the same problem with a client uploading photos. I took them into a picture program that does batch file conversion formats (ACDSee) and "re-converted" them into jpgs and they uploaded fine. They were jpgs to begin with.

Hi Capt,

Can you post an url (or attach a file) of the image that causes that error? I'll try to reproduce the error locally and see if I can figure out whats happening.

Sometimes when I'm not at the office I still login and answer some of the "easy ones" :)

Yes, that's definitely the problem. The simplest solution would be to delete the image, convert it to a jpg on your computer and re-upload it as a jpg.

Do you anticipate many users might have misnamed images? We could look at adding error checking for if the file extension didn't match the image type.

There doesn't seem to be much support for manipulating bmp images in PHP though, so it would be harder to support them directly.
