In many instances photographs used in articles might be obtained from social media accounts or even Facebook pages. Is acknowledgment of photograph sources needed in such a case? If possible how is it done?
Yes, you have to reference to social media as to any other references. See for example, APA 7 reference system, they have rules for referencing to social media.
Some articles have it this way:

Dear Prof. Teh Exodus Akwa & all the respected RG colleagues,
If you refer to any material, including images and data, you should be clear and define the source.
Because images are treated as data in this case, you should refer to any taken image and cite it in the references even it is a social media image. By the way, please do not forget that "A picture is worth a thousand words"!
On the other side, I think that your question should be "If photographs are uplifted from journals, does plagiarism apply?" instead of "If photographs are not uplifted from journals, does plagiarism apply?"
Plagiarism is a common problem facing almost all professors. This respected portal (i.e. RG) defines plagiarism as:
The term “plagiarism” has different meanings, but it usually includes copying somebody else’s work without permission.
On the other side, self-plagiarism is when the author republishes portions of his/her own previously written research work while authoring a new work.
I may be somewhat old-fashioned, but please have a look at the following golden principles on how to avoid plagiarism in academic writing, especially Self-Plagiarism:
Never use the "Copy-Paste" trend: Use your own words instead of copying and pasting the text verbatim from others (i.e. reference papers). Needless to say that if you are using your own words, then there is no chance of plagiarism accusing. Try to paraphrase your content as much as you could.
Never repeat yourself: There are many re-published articles that are slightly or even considerably modified, and still not changed!
If you have co-authors, just trust your words!
If you use your own words, there should be no plagiarism issue. In turn, there is no need for the tools of plagiarism checking. Since there is no guarantee that the original content of your manuscript might not be copied and sold to others before it is published by you, I discourage using any free-software checkers for plagiarism; some of them are betrayers. Despite that offline ones are rare and if you are insisting to use anti-plagiarism software, offline checker programs are safer than online ones. On the other side and in case you are again insisting to use anti-plagiarism check, the process should be carried out for the entire research work, literature reviews, for instance, are not an exception.
In some cases, you can paraphrase the sentences (إعادة صياغة الجملة) in the original document. But don't forget to cite the reference.
You must always insist on honesty. Furthermore, you have to always remember that there should be a new added value.
You must always insist on doing real research, not "Wikipedia" research.
Do not put any of your research work anywhere until it is published and tagged with your name. Please wait until the paper is accepted and then published in that journal. Then, upload that research item on any platform you wish.
In my opinion, most of the free-software-checkers for plagiarism don't work effectively. Unfortunately, you have to pay for the sake of getting good results.
Despite that offline ones are rare and if you are insisting to use anti-plagiarism software, offline checker programs are safer than online ones.
Try to develop your own style for the text writing.
You should be should beware of storing your document in any portal that is used as free software checker for any language.
Try to read as much scientific literature as possible, especially in your own research field area.
Don't forget to cite your Sources: Identify what is needed and what is not needed to be cited. If you refer to any material, including images and data, you should be clear and define the source. Because images are treated as data in the case of citation, you should refer to any taken image and cite it in the references even it is a social media image. By the way, please do not forget that "A picture is worth a thousand words"!
A reminder for all respected researchers: In order to maintain research integrity, plagiarism (الاستلال) has to be given up. However, many people do not know whether they are committing plagiarism intentionally or unintentionally.
Now, I think that the above-mentioned rules are helping in setting boundaries to avoid plagiarism in general, and self-plagiarism in special.
Finally, believe me, or not: If you make one plagiarizing, you may solve one problem and fall into many others where some of which may be described as a knockout. Again and again, please always remember that if there were accusations of plagiarism, it is not well for any researcher's reputation, in any meaning.
