The biggest obstacle most people have is
cropping their photos and then
resizing them.
In order to crop your photo, that means cut out just the important part and getting rid of the fluff, like grass, pavement or blue sky surrounding your "object" so that the majority of the picture is the object. The fluff surrounding your photo just takes up precious space.
I'm lucky in that my Canon camera came with a free version of Elements, which as near as I can tell is a cut down version of PhotoShop. I mostly use it to crop photos, especially if it's before and after shots.
Last I checked the paid for version was around $80.00, and the full PhotoShop software is even more. Because for most people they don't "need" software to crop photos most people don't have something like Elements or PhotoShop.
There are other photo software programs and some are even free, I think Gimp is one example but I don't know how to use it. If you need a program to crop photos I'm sure with a little Googling you can find one.
I included the link to a place you can crop photos online for free in one of my articles, this one,

Next you need to resize your photo because it's bad netiquette to post photos that force your reader to have to horizontal scroll. I outline why in my resizing article using Easy Thumbnails.
My personal preference and recommendation is to resize photos to a max of 800 pixels wide before uploading. I know others will post larger photos but anything larger and too many people will have to horizontal scroll. I usually just click away as I won't hassle with oversize photos.
I've been using Easy Thumbnails for resizing for probably 7-8 years, it's free and works excellent.

If you don't have any software to crop our photos you can always do these two things,
1. Frame up your photo so that what's mostly in the picture is the object.
2. Just resize what you have and don't worry about cropping.
If you're the kind of person that's going to be interacting with forums for the long run, whether car detailing or some other hobby or profession, then in my opinion it's going to help you to invest some time into learning how to work with photos on the Internet. That includes,
- Cropping
- Resizing
- Uploading
- Inserting
Attaching a photo is lame but I understand why people use that option.
For what it's worth...
