Making a picture into a poster +k

Take it into a print shop on a flash drive. I know some Fedex stores have a printshop inside. They could easily do what you want for very cheap. Hope that helps!

thanks! will it be all pixely though if i make it larger?

The guys at the shop can tell you better then I, it depends on the resolution you made it in.

If you plan on enlarging/ shrinking you have to make sure you do it proportionally. First convert pixel dimensions to inches, you can do this with a quick google search which will find a converter. Then make sure when you enlarge, you enlarge proportionally, so that length and width stay at the same ratio. What i mean is, don't just add on 10 inches to the length and the width, this is un proportional and will distort your image. What you need to do is add on a percent to each dimension. For example: say you have an image that is 20x30, making it 40x60 would distort and stretch it, instead, you would want to find (say 20%) of the length and the width, then add that on. so it could end up something like: 24x36 (following the 20% enlargment)

do you have a higher res image? You want to start with the highest native resolution, and then you will likely need to upsize it from there. I have a local camera shop/photo lab, and there is a guy there who helps out with all sorts of photoshop things. If you have a higher res file you can upload, I can take a look, and I'm sure there are also people on here who could do it better than me to get it to the point where all you would need to do is bring in a flash drive and you would be good to go

It depends on the resolution of the image. You are going to want to aim for 300 pixels per inch. You could go lower but it's going to start to look noticeably more pixely. So figure out your resolution and divide by 300 and thats the amount of inches that it would look good at.

make it a vector image(google it) you will be able to size it around and keep the good quality.

hahaha epic, but yeah you'l need to take a hi res copy to the printers

It's pretty difficult to get it as a vector without distorting the image. Nearly impossible with the text.

thats what I thought also, but something like perfect resize may work (I think it used to be called genuine fractals)
