Your article had a suspicious-looking link to scaler DOT com(a commercial training site) buried half-way down. At least five trusted users agreed that this made it look like spam, so your article was removed.
Assuming that wasn't your intention, I'd suggest resubmitting the article without that link.

I have noticed several recent incidents of submissions being approved, as Articles, that fall way short of the criteria for that category. They should be Tip/Tricks or Projects, have often been flagged as "Wrong type" by multiple reviewers, but suddenly show up on the home page after being approved by "Editor or trusted author". Whatever is going on here is unfair to authors who must actually resubmit under the Tip/Trick category.
What is the legal issue with images in articles? For example, can I put in an article image that is part of some company marketing material and publicly available, with a quotation of company material? Or some other image from some company website, with a quotation of Url? Or an image from some Pdf material, that is distributed publicly? Or how about a screenshot of some application forms, with the quotation of the company and product name? Or a screenshot of some hardware?
I looked at https://sarafhawkins.com/copyright-fair-use-and-online-images/, and it looks like as long as I am writing a tutorial or research, I can use images from 3rd party sites....
#2: Why are you using the image? If it is “…for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research…” you’re on the right track.
Only a judge can really make a definitive ruling on fair use. Speaking to the law, I'm afraid, is out of my jurisdiction.
Here's how reusing images goes: No one notices. It's poorly policed. Possibly a DMCA request if someone did. Haven't seen one ever. But that doesn't mean we shouldn't do our best. As a site of authors, we don't want to be willy nilly taking and reusing work from another author or company.
Since I can't give you blanket permission, can you just tell me what image you want to use?
I understand it will be based on a particular case, the decision needs to be made regarding approval from the case to the case...
For example, screenshots of different mapping applications/products, as a part of the tutorial what the current technology approach looks like.
I'm a software developer from China. I used to browse CodeProject a lot. There are a lot of technical articles here to learn. But for the past year or so, the website has been loading abnormally, probably because ajax.googleapis.com and codeproject.freetls.fastly.net cannot be accessed in China. Can you consider changing a CDN?
The way you edited my article  and decreased the size of images permanently, seriously damages the quality of the article and decreases the quantity and quality of info for readers.
I have noticed that in the article  you edited it so that images are permanently decreased in size to ~640 pixels and are no longer clickable, which were in the past resulting in the pop-up full-size image. The result is that images are so small that are not readable and the quantity and quality of info for the reader is diminished. I think you are doing damage to articles in that way by applying a “uniform look” to the articles.
The article is about different GUI solutions, meaning comparing GRAPHICAL representations of different tools. I invested time and effort to select proper screenshots and marked with arrows points of interest. The result was maybe 30 images, from 200-1000 pixels and I uploaded them to the article. I DELIBERATELY didn’t shrink them as I wanted them to be clickable (a feature offered by your editor) so the reader can click and see all details. Now they are shrunk and useless.
I saw that your article editor suggests shrinking images to 700 pixels, but most people today have monitors 1500+ pixels wide and want to see all details. Maybe your policy of 700 pixels images is outdated since today many readers want to see more details and have hardware for that.
I noticed a similar problem with other articles when showing class diagrams, if they are shrunk, they get unreadable.
I think that allowing images to be clickable and pop up in full size is beneficial for articles that contain a lot of images, for example, articles about GUI tools. I like the way it is still in the article .
By default, when you upload a large image the article should only display a tinier one, which, upon clicking, would show the full size version. The only reason we ever intervene to change the image is if this is not working properly. Which happens from time to time.
I've made a note to the editorial team to not shrink down your images, and if they must do so, to make sure they link to a bigger image when you click it.
Do you happen to have backup images for these articles? If you email them to me (firstname.lastname@example.org) I'd be happy to fix them all.
Should be all fixed! When creating the article make sure you use the (insert) button for each image to specify the larger dimensions. Otherwise it creates its own default max width of 640 pixels. I have communicated this to the editorial team as well.
