Trying to open documents scanned to TIFF files (has to be done this way, can't be scanned to PDF) off a network drive is very slow. I think I've found the problem, but have no idea how to fix it.

Windows Picture & fax viewer, and Office picture manager both appear to cache other pictures in the same folder when you open a picture so you can use the arrows to move between them. I installed irfanview & set it up to not cache the pictures - they open instantly set up like that, but the documents aren't readable in irfanview whereas they are perfectly readable in the other two.

Is there any way to stop office picture viewer from caching pictures?

No ideas anybody?

How about a free image viewer I can set up to not cache the pictures & won't make them look horrible like irfanview does?

Could be the tiff files.

Save them as something else, or dont load them from a networked drive.

Dont think a lot of people here, would be loading pics from a networked drive.

Did u try Irfanview with the plugins?

What documents?? Tiff files , or tiff files in a document?

Isn't it nice that they have thought up a way to help you by having all the pictures in a remote directory cached? It would make access so much faster (if ... you ... were ... prepared ... to ... wait ... a ... long ... time). :badpc: I once struck a similar problem when trying to look at small text files on some remote FTP sites. The local proxy server was trying to cache the directory before giving me the small file. The trouble was that those directories held gigabytes of files. :(

Are you starting the MS viewers manually or are they started by a browser when you access the file? It might be a browser setting in that case.

Would the Gimp (probably overkill) behave more sensible?

It could be some tiff files are rather large compared to other formats, and dragging them across the network requires them to cache before they open correctly. As you mentioned it could be the viewer itself.

Try using another viewer , plenty Here from this site (http://www.freeware-guide.com/dir/mmedia/imagedit.html) you can try.

As a comparrison, I just opened a 975Kb bmp photo across my network from the server in about 1 sec - opened instantly from windows pic viewer.

It is for a client. All my usual contacts are just as stumped as me, so I asked here.

They have a specialist program they use & they scan documents to tiff files through that & the link to them is stored against the customer in the program. When they want to refer back to the scanned documents, they look it up in the program & it does a shell open or something to directly open the picture in the default viewer.

The lease was up on their old computers, so we replaced them all & after it was too late to look at the old setup again, they found this problem. They have no idea what they used to open the pictures with.

I haven't tried irfanview plugins. Do they have one that may make the documents clearer?

The tiff files are really small - they are scanned in black & white, but there are a lot of them.

Wouldnt have a clue what the irfanview plugins do.

I dont use Irfanview, or the plugins.
