What Size is that Image
Recently I was having a conversation with another blogger about the size of their images on their blog. I am sure I have spoken about this before, but I thought it might be good if we talked about it here again. There are many people who are uploading their images onto their blogs that are full size, high resolution images.
There are three main reasons for not doing this. The first one is because you will run out of the amount of upload limit that WordPress allows you to use. I pay extra for my blog, so I am allowed 13 GB, of that I have used 2.6 and I have been blogging for three and half years. My images are small, I only load images that are around 250 KB, but I have seen some people loading images that are up to 4 MB. That is a lot and a very big file.
Another problem with doing this is that it means when people come to your blog to check out your images, your site can very slow to load. People aren’t as patient as they used to be and if it doesn’t load quickly then they might leave. It might seem to load quickly on your computer, but there are many parts of the world where the internet is not fast, Australia is notorious for it.
The other reason for resizing, really, is to protect yourself. I don’t know how many times people have told me that they have found someone using their images without their permission. The images are usually found on the internet somewhere. What about the images that you don’t find on the internet, but because you have loaded full size images, they have been saved and printed somewhere?
You may not think that it is something that you need to worry about, but many of those people who have found their images elsewhere have said the same thing, “who would steal my images?”. The reality is none of us think our images are that great and worth stealing, but there is always the possibility that someone does and someone will. You just never know.
So the next question I suppose is, how do we resize our images, and to what size?
There are so many ways of doing this, nearly every editing software that you can think about will allow you to resize an image. I could go through each one and tell you how, but then again, I could google it and see what I find, and guess what? I found a site that explains how to do it for several different types of editing software, so I think this would be a great place to start.
The next question is what size? I started by resizing my images so that the largest edge was 600 pixels, I have changed that over time, mainly since I got the larger monitor, so now I do it to 800 pixels, not that much of a difference, but enough so on a big monitor you can see the images better.
When I do them individually I also make them 72 dpi (dots per inch) so they look good on a monitor but not when printed. However, since I have discovered batch processing in photoshop, I can’t always do that anymore, though I have just recently worked out how to get rid of the metadata in the images.
Meta data is another thing that some people think you should remove. I am not so certain, supposedly if you remove it then you can prove that the image was yours because you have the image with that information on it. The metadata is the information that your camera attaches to images, like what ISO you used, what aperture, if a flash was used etc. If you click on an image and go to properties you will often get all that information. I work on the theory that I will have the full size high res image to show that it belongs to me, and I will have the images around it as well.
I think we should all do everything we can to protect our work, whether you think it is valuable or not. So please take care of your work and don’t put up big images so anyone can take them, you just don’t know what they could be used for.
Introductions – Victor Rakmil last week, well Victor let me know that he has written a post on how he does Macro photography, and I think for all of you that are interested in this type of photography it could be a great thing to go and read.
