Can someone explain how images are handled in FMP 12?

Hello

I have some questions about images in FMP 12 that I'm hoping someone can clarify.

I have a solution that was converted from 11 to 12. In 11 it had stored images in a conatiner field. I know that even after you set up the remote folder to store container field contents, for a converted solution, you need to actually tell it to move them.

Q1: There is the option for storing thumbnails, does this increase speed for a solution hosted on FMP server?

I've had a lot of problems with generating large PDF file sizes on some layouts. After extensive testing using GetThumbnail and not using GetThumbnail, I'm still confused. In general, it seems if GetThumbnail is set above 370x370, the PDF file size is huge. If GetThumbnail is set to 370x370 or smaller, it's pretty manageable, but image quality isn't great.

Now, on some layouts, I found that the PDFs were significantly smaller than what Save As PDF generated in FMP 11 and the PDFs created using Save As PDF in FMP 12 were a great file size. I saw that on layouts that were set to 9 records to page and print in 3 columns across.

The layouts I have problems with are 4/pg, 2 columns across and 3/pg list view. I thought maybe container dimensions had something to do with it, but no, that does not seem to matter. Container dimension on the 3/pg list view layout are smaller than dimensions on the 9/pg layout.

Q2: Does FMP compress images and if so when? Does it compress images when creating PDFs and if so when?

Any insight is greatly appreciated. For now, I'll be using GetThumbnail set to 370x370 on layouts that seem to need it, but I'd love to know why they need it and why 370x370.
