Problems with image upload

[envexlabs]

Hey,

 

I have an image uploader script which uploads then resizes the image. The script works fine except when users are trying to upload an image from a camera.

 

This is the error people are getting:

 

Thanks,

what's the error say?

 

could you show us the snippet of code that gives that error?

 

did you write the script or did you find it online somewhere? My guess is that the script is only set to work for .jpg or .gif images and data coming from a camera is either in raw format or has lots of extra meta data that the script can't handle.
