Image function etheme_get_image not working

Some mods were made to a few woocommerce template pages but that was in 2013 and nothing has been updated since and etheme_get_image has suddenly stopped working. I can’t let you update the theme because of the mods. I saw an earlier post about permissions – what do they need to be set to perhaps that is my problem although it seems strange that it was working fine and now suddenly the function does not send any value back but blank and the lightbox does display the images. Can you tell me what the function is trying to do here is the function in my version of the theme let me know if it has changed

Attached is the access

Yes the image folder permissions are correct.

Please retry with the attached.

The file permissions have been updated on that directory please try again. I do see images in the featured image section but it is also showing the path to the image but still nothing in the single product page.

Eva – do you have any reason why I now see the featured images on the home page but with the url above them when I saw nothing before? Why would it suddenly stop working if nothing has changed?

Thank you.
