Delete Image Sizes?

Hi I have 7 different image sizes. 3 are from my Theme (with add_image_size()) and I have probably created the others myself with Simple Image Sizes. But I am not sure. I want to delete the image sizes created with “Simple Image Sizes” now. So that I can see which ones are generated by my theme or other PHP codes (with add_image_size) and which ones were created by “Simple Image Sizes” plugin. I once uninstalled the plugin to see if all the images created with “Simple Image Sizes” will be deleted. But when I install Simple Image Sizes again, all the Image Sizes are back. Can one see somewhere, which were generated by php code (with add_image_size) and which with the plugin? So, is there maybe a reset button? The All inputs removed from the plugin or shows what was created by the plugin? I would be very happy to receive an answer. P.S. .: Generally it would be very informative and helpful for others if you can see which image_sizes were created with the Simple Image Sizes “plugin and also a feature that you delete this image_size and maybe the image sizes (maybe export before) could. That would be very good. This topic was modified 6 years, 8 months ago by DjPD .
