| Export with hidden alpha channel |
|

Hi all, I have a question about alpha channels. When I click the eye icon next to the alpha channel of a layer to hide it, then export it to PNG, the exported image still has the alpha channel. However, removing the alpha channel entirely produces a different, unwanted result, turning the image blue-ish. This blueness is kept when exported.
Is there any way I can export my image to a PNG so that it looks like it does in GIMP with a hidden alpha channel?
Thanks!

I have a significant number of jpegs that require editing.
I prefer to save my edits as png doing the following:
(1) Shift+Ctrl+E
(2) Alt+T for Select File Type (By Extension)
(3) mouse click on "By Extension"
(4) Type "png" press Enter
(5) Alt+E for Export
(6) Alt+E for Export
As you can see, I use keyboard shortcuts and do so rapidly. However, for such a large volume of jpegs, this becomes time-consuming and laborious.
Is there any way to automate this process? Grateful to hear if there is a way to do so.
Many thanks

| Can't export raw data without alpha channel if image contains more than 1 layer |
|

Hello,
Why is it that raw data export always contains alpha channel if the image has more than one layer?
I have image in RGB mode with multiple layers and would like to export each layer as individual raw data file containing only RGB data (i.e. 3 bytes per pixel).
But I cannot get the file exported without alpha channel being saved as well (4 bytes/pixel). I have made sure alpha does not exist in any of the layers (selecting "Remove Alpha Channel" on all layers). If I delete all but the layer I want to export, it is exported without alpha like I want.
I am working around this now by copying and pasting each layer to a new image, removing the alpha channel from that, and exporting the new image to raw file.
Even that would be quick to do if all steps had key shortcuts, but the alpha channel removal must be done with mouse still which slows down the process (select layer, Ctrl-A, Ctrl-C, Shift-Ctrl-V, remove alpha with mouse, and finally Ctrl-E).
Is there some setting somewhere that says multi layer images always contain alpha channel, even if individual layers do not?
Thanks in advance,
Tomi

| Windos won't open JPG after editing in GIMP |

I've been using GIMP for many years and have never had a problem such as this. I did some minor edits in a JPG image. I then export it as a JPG. Now windows doesn't seem to recognize the image. The thumbnails come up with a default image icon and when I try to open the JPG in Microsoft Photo, I get an error message "It looks like we don't support this file format." No other windows software seems to be able to open it but GIMP has no problem opening the image. I have tried renaming it file and saving it with a different name with no change in outcome.
I'm running Windows 10 v.20H2 and GIMP 2.10.22
