I need to know if there's a way to increase the size of an image without losing the quality in Photoshop please.

Thanks

no, fraid not

Can't be done in any other software either.

It can be done in a vector based program.

Depends on the graphic you want to enlarge. You can try a live trace (Illustrator) or similar and then resize it.

Should there be a minimum size in pixel or something to do this?

If the image isn't complex, you could pull it into illustrator and LiveTrace the image, turning it into paths and then you're free to expand it as much as you want.

If it's a complex image (like a photo) you could increase the size a little with no loss of quality IF you reduce the dpi.

So, for example, if your image is 100mm x 70mm @ 300dpi, you could reduce the image to 72dpi and enjoy the file at the new size of 416mm x 291mm.

If the image is already 72dpi, and you need to get it larger anyway, you could try the following:

1) Blow the image up by the required amount plus a bit more.
2) Blur the image a little
3) reduce to the required size, and sharpen.

This sometimes gets decent results, but it's fiddly and requires a good bit of work. Have a play and see how you get on.

only the PRINT size and i assume we're talking about an image destined for screen use. incidentally we should be talking about ppi (pixels per inch) : it's only dpi when it's printed (dot per inch)

It really doesn't make a difference either way though, does it? DPI and PPI are essentially the same thing.

it's a small thing but one that is repeated all too often - just thought i would clarify

Clarification is an elusive quality in my life.
