Hi, I am creating an instagram carousel in photoshop - i.e. a very long canvas. I created a new blank canvas with the custom dimensions of 1350 for height and 9720 for width (it will equal 9 slides that are 1080). I added multiple images and then split the canvas into 1080 sections. When I go to export Save for web legacy, it shows that the image size is 8192 W and 1138 H. That's odd. When I try to change it to 9720 and 1350, it gives me this error. So I went with it to see what the images would look like but that has reduced the quality of my image slides. I go back in and double check that my canvas size is still what I put it as and sure enough it still is 9720 + 1350. So shouldn't the image size in export match that? If so how can I change it?
Oh and to clarify - in the first screen shot the error shows that I was exporting it as a GIF. I just did it quickly to reproduce the error for the screenshot. But I was trying it as a JPEG and that's what I want is jpg format - multiple (9) images to come out from this.
8192 pixels H or W is the limit for Legacy SFW, so it will reduce your canvas to that amount as seen in the bottom right of the SFW dialog. Try File > Export > Export As > and choose jpeg in the dialog menu. It will allow 9720 px.
(I have to double check things, but that way you have good information).
Oh That's interesting! So I tried that and yes it now shows 9720 + 1350 and the quality looks so much better - however, now it saves it as one long image instead of exporting 9 individual photos from the canvas. I don't know why "save for web" process knows to automatically split the images where I have spliced them, but the Export > Export As > jpeg option doesn't retain the splices. So now is there a workaround for that?
I've never tried to split an image before either in SFW or Export This video gave a clear idea if what you are doing and unfortunately SFW is recommended because it generates
images from the slices. So this is where I'm stuck.
So now we know SFW reduces your panorama to 8192, but exports the slices. Export > Save as Jpeg can't export slices.
So if no one answers this problem, start a new topic explaining the situation.
Okay thank you I'll wait and see if someone else knows the answer! Thanks for your help.
You could use View>New Guide Layout to divide the image into 9 sections, use the Rectangular Marquee Tool to Layer>New>layer Via Copy each section and then select all 9 layers right click and use Export As which should save thiose 9 layers to separate trimmed files.

Why create another topic?
I have added a script in the other topic to automate the process of splitting the image into columns and rows.
