I might be wrong about this but I believe GIMP will read multi-page TIFFs but cannot write multi-page TIFFs.

What is the best way to solve this problem?

When you open the TIFF, select open to layers. The first page will be the bottom layer. Turn off visibility of all the other layers and make sure the bottom layer is active in the Layers dialog. Then you can edit that page.

When you save, save it as a multi-layered PNG. Then use ImageMagick's "convert" tool to convert it to a multi-layered TIFF:

convert file.png file.tiff

That should do it (I think), though I can't vouch for the quality of the conversion.

When you open the TIFF, select open to layers. The first page will be
the bottom layer. Turn off visibility of all the other layers and make
sure the bottom layer is active in the Layers dialog.

How do I do these 2 things? What is the step-by-step process for doing these things? I am a Gimp newbie.

Well, obviously the Layers dialog has to be visible. Then you click on the eye icons next to the other layers, so they disappear, and click on the bottom layer to make it active.

Then
you can edit
that page.

When you save, save it as a multi-layered PNG.

Then use ImageMagick's

"convert" tool to convert it to a multi-layered TIFF:

Is there a difference between multi-layered and multi-page TIFF?

I'm pretty sure that was a typo.

What is the best way to solve this problem? I have tried this:

I right-click on the file on the Windows desktop, then select "Edit with Gimp". Gimp's "Import from TIFF" dialog is displayed. I click the "Select All" button. Now, I must choose either "Open pages as layers" or "Open pages as images".

If I select "Open pages as layers", the last page of the document is displayed. How do I display the first page?

If I select "Open pages as images", each page is displayed in its own window. I can then edit the first page, but if I save, only the first page gets saved. How do I save ALL the pages, and in the same page number order as the original TIFF file?

Is there a better way to accomplish my goal?

Yes.
Unlkess yiu really need to hand-paint each image, at 1000 pages it would be worht writing an specific program to deal with them. SInce you have "GIMP inplace, instead of a full porgrma, a gimp script propbably would suficce. Depending on your intent with the first pages, a script for that could be written in weel under an hour, and a modern desktop could jhandle your 1000 files in couple of hours.

But..for your infrmatiom, what you are missing is the way to handle "layers" in GIMP:
weh you "open as layers" each of the image's pages is placed in a sepoarate layer - that is, they behave exactly like pages stacked one on top of the others. To be able to ciycle trhough the layers and view different ones, you have to looka t the layers dialog (Dialogs->layers, or just hit ctrl + l) Open an image as layers, play a ittle withthe eye icons, and rrows, and layer selection - you should figure out how they work.

And tehn, unless your changes absoltuely can't be automated, get back to the list asking for advice on a script to do what you need.

Thanks for your help.

There is nosuch thing as "multi-layered PNG's" If GIMP can't save multi-page tiffs (and it might not, I don't rememebr now) , kindly ask for this functionality on this very list and we shall see what could be done. :-)

That should have been mng, not png. I didn't check my notes before replying to the original poster.
