Help - can an image with 96 DPI be upgraded to 300 DPI?

[xkrsupercharged]

I have an image I would like to use in a printed magazine and the publishers have said my image needs to be 300 DPI. Mine is 96 BPI.

The pic is owner by one of my suppliers who have authorised us to use the pic but they do not have a higher resolution image.

Can anyone on here help increase the DPI via a any kind of software - photoshop etc?

I have found this online but I dont have photoshop:

"Open your pic in photoshop and resample it at 300 dpi and at 200% its original size.
Then, scale it down manually from one of the corner handles. The end result should be quite crisp."

Any help appreciated

Thanks

As you can see I have no idea what they are on about. All I know is that they have told me that the pic as it stands cant be used as it needs to be a minimum of 300 DPI.

If used it won't print "clearly".

Any suggestions?

Thanks all - it's sorted. The publication's artwork studio sorted it themselves in the end

Didn't realise I'd start a debate LOL
