<p>[QUOTE=&quot;calcol, post: 26164415, member: 77639&quot;]After doing some research, it turns out that some (all?) Android phones create a thumbnail that is embedded in .jpg images they create.&nbsp; This “feature” can be turned off with some manipulation but may be enabled again at the next OS upgrade.&nbsp; Editing the images will usually not remove the thumbnail. This may seem trivial if cropping out the label of a slab.&nbsp; But what if names on a legal document or secrets on a company document needed to be cropped out?</p><p><br /></p><p>One thing that will remove the thumbnail is to convert a .jpg file to a .png file.&nbsp; This is desirable for editing anyway.&nbsp; Many folks don’t realize it, but if a .jpg is edited, the new file will usually be changed in ways other than the edit.&nbsp; This is due to the lossy compression algorithm used to create .jpg files.&nbsp; After successive edits, the entire image will have less resolution compared to the original.&nbsp; The downside of .png files is they are significantly larger than corresponding .jpg files.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
