I am not familiar with photoshop and thought it would be a snap
to convert a picture from one size to another, but I can't figure
out how to do it...I have an image that is currently 96 X 65 pixels
and I wish to have it printed on canvas. The shop where I'm having
it printed said it must be at least 500k in order to maintain the
integrity of the picture...I have NO IDEA how to do this, or if can
even be done!! Anyone?
If your image is truly only 96 x 95 pixels it's going to look like a big blurry mess if you try to print it any larger than a postage stamp.
Photoshop is great software, but it can't make up image information that's not already there. That only happens on TV shows.
I don't know how big your canvas is, but you'll want at least 150 if not 300 pixels per inch, depending on how close you expect someone to be when looking at it (bigger prints are usually viewed from farther back). So, for example, if the canvas is 24 x 36 inches, you'll want your image to be something like 3600 x 5400 pixels. Your print shop's recommendation of 500k (assuming they mean a JPEG of 500 kbytes on disk, which has little to do with pixel dimensions) doesn't seem like enough, actually.
Thanks Noel - the print is going to be 30 X 20 inches, so I would need
to convert the image to handle that size. I am getting from your post
that is not likely or even possible, even using Photoshop? When I enter
those dimensions under "Image Size" in Photoshop I get a width of
15000 pixels and a height of 10000 pixels with a resolution of 500 pixels
per inch. I sent a copy back to the printer to see what they can do with
it...they probably will just laugh!! Thanks again for your input. I purchased
the canvas print and now I don't think I will have a proper photo to have
printed on it!!
You would get 4500 x 3000 pixels if you chose 150 ppi, which is a minimum that you really need at 20 x 30 inches but as I said, your starting image is just too tiny to be printed at that size.
Oh, but the strange thing is, I had this very same picture
printed at Office Max into a 24 X 36 picture and it turned
out beautiful. I then pasted it to a canvas and framed it.
I thought I could use the same image to print directly
to canvas, but I guess I was wrong. I don't understand
why one could do it and now the other cannot - ?
Anyway - thanks for your input!

Are you *sure* it's just 96 x 95 pixels?
This image, for example, is 96 x 95 pixels:
If you liked how it looked on a smooth print, you'll be happy with it printed on canvas. I'm betting it's actually bigger than 96 x 95 pixels, or you printed from a different file before.
And full testament to the fact that small can still be scary.

But of course she printed from a different file before! No printer on this planet will remotely accept a 96 x 95 pixels image file to print even a wallet-size picture, let alone a large canvas print. … and if they upsample it like she says she did, the shop staff must still be chuckling about it.
What the OP needs to do is look for her original file and forget about that 96x95 pixel miniature.
…the print is going to be 30 X 20 inches…
That is not even the right aspect ratio. 96x95 is a ratio of barely over 1.01, which means it's practically a square (like Noel's example), while 30 x20 inches is a ratio of 3:2 or 1.5.
Somewhere along the line you've lost track of your original image. It almost sounds like you are looking at a very small thumbnail preview somewhere.
The only way this could work, as you have phrased it, is if you have a picture of an absolutely cloudless, perfect blue sky, practically nothing but a blue patch. Now a blue patch can be resampled and cropped without loss of quality.
