Need help, please, thumbnails not working.

[shibby2]

Hi, I have a vb 3.8 board and when anyone tries to upload an image, it wont create a thumbnail, just gives a text link. When you click the text link, the image opens in a new window as it should.

All settings are correct, I've gone over them a million times. Attachments are stored in the database.

Also, I have size limits in place for uploading attachment images, but it doesnt seem to work. If an image is too large, it just wont upload instead of re-sizing it automatically.

Any ideas?
