I try to add item image, the caption and credits are contained - but the image is not saved (no error msg as I can see). When clicking "image" in the Item, I see the caption/credit, but no Image, just the upload field + browse button once more as if no image had been uploaded. All settings worked very well running locally using xampp.

After uploading first image (after installation), the media/k2/items/cache folder is populated with 6 files (the different sizes). The names are _Generic.jpg, _L.jpg, _M.jpg etc. All these are without the prefix - leading me to believe there are some function that generates prefix that does not work?
The media/k2/items/src folder has not been generated - I do this manually (+ chmod 775) and try adding another picture (through the Item -> add Image) - but all this does is to replace the pictures under media/k2/items/cache (and nothing is put in /items/src). So again - this leads me to believe that the generate prefix function (before _Generic.jpg etc) is broken somehow....

I have also tried very small pictures (in regards to another similar error her)... to no help..

Can anybody help me with this?

Hi. This is weird. The prefix is generated by the id of the item so this should not be empty! Are you still getting this error?

Hi Lefteris - thanks for your reply.
Yes, I am still experiencing this - it is very strange (and quite frustrating :). The _Generic image keeps being written over, but no prefix is added.
I see from my local installation (xampp) that the prefix is a rather long and cryptic string so I guess there is a function that generates that string on the basis of the item id (I found no connection between image and item in the database). Could it be that that function uses some kind of generator that has "special" needs for certain settings on my server (random generator, file-permission for temp storage etc)?

No there is no special requirements for this to work. Please check that the folders are writable and try to create a new item with an image. Please let me know if you get the same error.

Hi,
made sure that media-folder (and alle sub-directories/folders) has permission 775.
I also did the same for the images-folder under root. (I use FileZilla to set permissions)

The result is the same - the _Generic file is overwritten with the new image, but no prefix is added and it does not show up in the image.

Thank you very much for helping me - do you have any other suggestions as to what I should try?

Hi again. Did you tried to create a new item? Please check that you can create a new item. The prefix is generated by the item's ID. What version of MySQL are you using?

Hi Lefteris,
yes I am able to create new items - and the id for the item is created (looks correct).

Hi again. This is very weird. The routine that generates the prefix uses php's md5() function. It seems that for some reason php's md5() fails. Is it possible that this function is disabled by the server configuration? I suggest that you do some further research on this as i cannot reproduce this bug and no one else has reported something similar in the past.

I too have this problem, all folder permissions are ok, but images don't upload - the server is configured ok to use md5 - any updates on this issue?

Are you having exactly the same issue? Or your images aren't uploading at all? Did you get any files in the directory media/k2/items/cache?
