changing resolution on existing images

about:

I have Photoshop 6.0 and I have a couple of cd’s full of images that were produced for me by a print shop. They are photos of artwork and have been scanned in at fairly high resolutions. I want to know if it is possible to change the resolution when I adjust the sizes of these photos and save them for the web. The ultimate goal being to produce images for the web at the lowest possible resolution necessary for viewing online, and then I’ll convert them to pdf files to make the "lifting" or "theft" of them more difficult for visitors to the site. Is changing the resolution possible? I’m not terribly experienced with Photoshop – I know how to do what I need to get by with my web site work so have patience with my questions! Thanks to you all.

You want to resample the images, not change the resolution. The first will reduce the number of pixels, the second retains the pixel count, but alters the (later) printed size.

See "Image Size" in your manual or "F1"

and/or download a freeware Irfanview http://www.irfanview.com/, and Batch convert..

You’ll just be wasting your time. A screen capture will get right around that.

File->Automate->Web Gallery

Allows you to control the size and compression of the processed images, plus makes a large and thumbnail size, which may be useful (it usually is for me).

I don’t think making the images into pdfs will stop anyone from lifting them from your website. A screenshot is all that’s needed.

Eric my apologies for replying to your private email! I meant to reply to the group with the following:

Yes I realize that screen capture will do it, and as I mentioned I am just trying to find a way to make it more difficult to take them. I don’t believe the average user will know to do a screen capture – not COUNTING on it but…. And with that said, any other measures you guys can think of that I can take to make it even more difficult would be appreciated! I realize that anyone with more that average skills on the computer/internet will be able to take them no matter how I try to encrypt, watermark, or otherwise manipulate the images. So I’m trying to make the quality of the online images as "unusable" as possible – I’m working with an artist and her works. Any other thoughts?
Thanks for the resampling tip!

Well, cheer up – you did.

That email has been public too long to be useful anyway. Fills up every hour or so with virus-ridden spam.

Just make the images too small for any print purpose and plaster the copyright all over the web pages and embedded data on the pics (you can turn on the watermark system in Photoshop – it will slow down some idiots).

Don’t mangle the pics with visible watermarks – you want to sell them, right?

You won’t stop some schmuck from using it on their WebTV free page, but there is no system that will not run off most potential clients before they see the first print that will prevent minor thievery.

Trust me on this one. The returns aren’t worth the effort.

Brooke, degrading the images to the point they’re unusable seems to defeat the purpose of displaying them in the first place. If you’re familiar with slices that might be a solution. Or (and I don’t much care for this but…) I see some people putting a picture in a picture, like a thumbnail sized picture overlayed onto the full sized image. Some even make the full sized image black and white. Another option might be to concentrate on key features of the artists work while using a thumbnail to show the whole piece. Hope this sparks some ideas… ~Doc

Thanks all – Eric and Doc your points are well taken. I will revisit this whole issue with the artist and see if we can find some middle ground to agree upon with this. Thanks again – ya’ll are always helpful!! Brooke

It seems to me that if what Brooke wants to protect is an artist’s work, merely resampling to 95 dpi in a size to fit on a screen would do that. The resulting image would not be reproduceable in any usable form for print, but would still show what the work looked like.

Merely resampling to 95 dpi, or 950 dpi or 1 dpi for that matter doesn’t change anything. If the size of the image on the web is at 800 x 600 (for instance) that is the amount of information presented. Period. If you send it to the printer without adjustment you might get a high res postage stamp but you might also get a low res poster. The quality of that information is another issue, which involves the degree of jpeg compression. All that aside consider that I employ a technique whereby I’ll intentionally save an image at the lowest jpeg setting then rebuild it to resemble a painting. It’s hit and miss but some of my results are impressive. Others are spectacular. The point being that the OP has a genuine concern about releasing such information on the web. ~Doc

Yes, however, the only sure way to prevent copying is not put the stuff there in the first place 😉

I usually find the beast way of doing things is (with photography in my case) shoot want I want, but take 1 or 2 specifically for the web as I know they’ll get stolen.
