I am using Gingerbread in my Android device. And I found these gallery caches & thumbnails under this location "../mnt/sdcard/Android/data/com.cooliris.media/cache/" in my file manager. I hope, this path will be same as I have mentioned above, in all other Android versions. Here, com.cooliris.media is a folder, created by Default Android Gallery. Here, some folders like "com.cooliris.media", "cache" will be hidden. So, change settings in your file manager or in system to display hidden files & folders. Generally, these caches will cause storage problem after long time as during long time-period, useless files will be increased.
So, follow these steps to remove caches and to free up memory:
► Go to your File Manager and open "cache" folder as given in above path.
► In this folder, there are many others folders like "hires-image-cache", "local-image-thumbs", "local-video-thumbs" etc.
► All these folders contains different caches & thumbnails as per their folder name. So, check the size of these folders and delete all files in them and get large amount of free space. You will not loose any images or videos in your Gallery.
► Enjoy lots of free space!!
