When I open a .gif image in Photoshop - non animated - it always locks automatically and you cannot unlock it. Aside from that when try try to add text it will make a red block and convert the text to bitmap.

You annoyingly have to copy and paste the document into a new document. Then layer from there.

It's due to the Index Color mode. GIF and PNG8 use a locked color palette, therefore the layer gets locked to prevent unsupported changes. It's also why the layer is titled Index.

To unlock it choose Image > Mode > RGB from the menu.

  • Can this be as a default? – TheBlackBenzKid Dec 3 '12 at 22:04
  • No. GIF and PNG8 images will always open in Index color mode, that's simply how those images work. When you save a GIF or PNG8, it gets saved to Index mode as well. – Scott Dec 3 '12 at 22:05
  • I'm not an expert by far, but I do use Photoshop nearly every day at work. I cannot for the life of me understand WHY this is necessary? I find it to be a huge pain in the butt to have to unlock or duplicate an image because it always comes into Photoshop locked and unable to manipulate. Shouldn't this be a choice someone makes instead of a default? – user22965 May 1 '14 at 18:00

    You can also simply assign a shortcut (via actions) to change the image mode to RGB and it will unlock the Index layer. – Scott May 1 '14 at 20:54

    You also don't usually WANT to be editing GIFs. Ideally, you're editing the original PSD rather than the exported GIF. – DA01 May 13 '14 at 18:18
