Hello. I want to edit the classifieds listing page. The part you want to change → We support image files of type JPG, JPEG and PNG files up to 30M with at least 800 pixels along one side. FLV, MP4, MPEG, MOV and AVI videos up to 30M and a minimum resolution of 800x640 pixels. I want to make it impossible to upload video files. I want to change the file size and resolution size. What should I do?
