I’m using WordPress 3.4.1 with the Suffusion theme 4.3.0.
I’ve noticed that there are a large number of images with hexadecimal names, like 54f96e1d5f478186f66bde9d6aeda625.jpeg. I’m wondering how these images are being created, and what I can do to prevent their generation, as they don’t seem to be used by any post.
Testing the plugin provided in this Answer, I just saw that
media_handle_sideloadgenerates exactly this pattern,jpegextension as well (instead ofjpg).Following its path through the core, it seems that only the filter
wp_handle_uploadcould be used for dealing with that.But a brief research shows an interesting use of
wp_handle_upload_prefilter: Rename files during upload using variables.A way of finding which element is using
media_handle_sideloadis:– drop all the plugins and theme folders/files into a good editor (NotePad++, TextMate, etc) and do a global search for this filter.
After finding where it’s being called, a rename strategy can be thought of.
All this assuming the Sideload is responsible in OP’s case
