picture file sizes

Hi all i have been trying to upload some stacked widefield pictures but the file sizes are to big, on average about 100mb. My question is how do i reduce the sizes to be website friendly?

There are a couple of ways to go about this. One, if you use Photoshop Elements, you can "Export to the Web" which will create a compressed Jpeg image that is much smaller than the original file.

Another way is to use "Dropbox" and place the files in a sub-folder in the "Public" folder. Then you create a link to the sub-folder and publish the URL to the link. How to go about this is covered in the users guide to the program.

There may be other programs beside these two that will either create compressed or linked files for you, but these are the ones that I use. Good luck !

I save a copy for uploading. I resize to 75ppi and set the longest side to 1000 pixels then use the save for web and devices command in PS.

If you search Google for free image resizing software, there's plenty out there that will resize, and also convert file types.

Once I've stacked my subs, they are saved as an uncompressed Tiff file which is approx. 90mb in size, and during processing I work with uncompressed tiff files. When I've finished, I save a copy as a jpg to post on here which will be about 1mb file size.
