Not sure what other types work, but JPG's do. Best size probably depends on the size of the window you display it in. I have expanded the display size on the RTM's (in the header section) to be about 2.5 inches square. By rearranging the RTM you could come up with any size you want, so you may want to play with that first. There are two available frames in the graphic traveler. I don't know if anyone has ever been able to get thumbnails to work in the routings section. I keep the thumbnails in the same mapped drive with a global path as my linked documents to keep things simple. It would be nice if there could be separate default paths between the thumbnails and links.
 

That's a really good idea, Probes.  About 3 years ago I visited a company who had converted all their work instruction binders to marked up pictures with captions and it decreased their production mistakes across the board ESPECIALLY with new employees.  If it could be done in Evo with routings that would indeed be '...2 birds...'

Thanks Lynn. FYI we just installed the 12/21/08 update over the weekend [I like the changes, too numerous to mention] and I took some time to try to get this functioning. We now have Evo Links enabled through SD-Q, and I entered a .jpg link using the Evo Links button through IN-B. It all seems very straightforward, however it seems to be lacking the area that explains exactly which routing sequence it should be linking too, unless I'm missing something. Using the old Item Links it would ask you which routing sequence to link [allthough it would never save for me], and I can't seem to find the equivalent using Evo-Links. I can verify the link path is correct because I get a preview, and oddly enough when I print using the default ENWOC3.RTM file it links the thumbnail at the top of the form, but doesn't actually embed it within the routing sequence. I'm soooooo close... -Mike

Hmmm...
IMHO, logical places to enter image links for routings would be:
 
RO-A. - Select or enter a sequence #, have an entry somewhere along the standard flow that allows you to do a quick file name entry, checkbox for 'global link path', and 'T' or 'L', [thumb or link]. I write my routings in a very systematic way, trying to do a very detailed step-by-step instruction set and would make sense to me for the link entry to be here, so as I'm writing my initial master routing I can easily keep things in check and not lose my place instead of having to enter all the instructions, then go back to a separate data entry sheet to link all my files. On that note, I write all my sequences in intervals of 10, and would appreciate if I happen to rename sequence 30 to sequence 40 that the link intelligently follow along...
 
WO-A. Why? - In the event you have to make a one time change to a routing that has already been converted to 'F'. Similar to the interface of WO-K-A.. wait, scratch that, WO-K-A is horrible.. but you get my drift. It might also be prudent to have it block change requests to 'R' work orders since they should already be 'Live and in production".
 
IN-A. Why? - It's probably the default starting place for most folks when they are looking for general information. At the least this could be a link to the same screen used in one of the above suggestions of not a separate entry form.
 
Oh, and BTW, while I understand what you suggested in your last post, it is still not properly printing on the default ENWOC3.RTM. Using IN-A to drill to the routing seems to be on the right path because it informs me I'm editing the link for P35-1206  -  40 [item # and sequence #]. At this stage my preview also displays correct. I'm linking a jpg file, its tagged as 'traveler', 'thumbnail' and 'parent'. Its also set up using our global path.
 
Oh, and on a possibly unrelated note, since the update to 12/21/08, none of my .pdf files link with the travelers when they print. I have to manually open the link through IN-A and print.   This seems like some simple problem I've overlooked which is adding to my frustration. Happy Monday!   And as always, I appreciate the help and input of my fellow forum users. We are such a diverse crowd with many backgrounds and specialties whom all seek a unified solution to our database problems.

I just looked at the RTM for WOC and "T"unmbnail is not an option in routings. It only woks for The Parent WO, or the BOM components.  
 
I did just however, add the ability to print them as Links. Thumbs would be something custom.

I don't know if there is a list, but as far as I know, Quotes, Acks, Pick Tickets, Packing Slips, Invoices, Travelers and POs all do.

No problem. They are there (make sure you have the latest RTM (copy from RTX).

If you are on the latest Update (April 2013) Links and Notes are now accessible by ODBC so Access, Excel, Crystal et al can be used.

I just finished maxing out my thumbnails.
 
I now have a thumbnail for every item, there are about 5,000 real thumbs and 15,000 that all point to a generic no image thumbnail. (camera with a No symbol over it)
This makes it so much easier to add a thumb to an existing item as each one has all the settings I only need to update the file name the link points to.
 
Also the reports all print with the same vertical spacing because it always prints a thumb for every item.
