Here are some of her comments regarding photos.
These photographs cost money. Is it consistent for us, knowing the work that is to be done at this time, to spend God's money in producing pictures of our own faces and the faces of our friends? Should not every dollar that we can spare be used in the upbuilding of the cause of God? These pictures take money that should be sacredly devoted to God's service; and they divert the mind from the truths of God's word. {RH, September 10, 1901 par. 3}
This making and exchanging photographs is a species of idolatry. Satan is doing all he can to eclipse heaven from our view. Let us not help him by making picture‑idols. We need to reach a higher standard than these human faces suggest. The Lord says, "Thou shalt have no other gods before me." Those who claim to believe in Christ need to realize that they are to reflect His image. It is His likeness that is to be kept before the mind. The words that are spoken are to be freighted with heavenly inspiration. {RH, September 10, 1901 par. 4}

Every dollar is required in the work of saving souls. The money invested by the professed people of God in getting pictures made of human faces would support several missionaries in the field. Many small streams, when put together, swell into a large river. {RH, September 10, 1901 par. 9}
The youth have their hearts filled with the love of self. This is manifested in their desire to see their faces daguerreotyped by the artist; and they are not satisfied with being once represented, but sit again and again for their picture, each time hoping that the last will excel all their previous efforts and appear really more beautiful than the original. Their Lord's money is squandered in this way, and what is gained? Merely their poor shadow upon paper. The hours that should have been devoted to prayer are occupied upon their own poor selves; precious hours of probation are thus wasted. {1T 500.2} [1855-1868]
We have a constant contest with idolatry. Many things which gratify the lust of the eye are taking precious time and stealing away precious money. The senses are pleased but God is robbed both of time and money. I am pained to see the photographs multiplied and hanging everywhere. {1888 887.3} [January 22, 1891]
However, here are her comments about her own photographic endeavors:
We received yours [i.e., letter] which contained the number of pictures to be sent. They are slow in getting them out. We send from Ingelson's seven each. We sent from Lathrop's and Dunham's, six each. You will see that Lathrop has the preference. I thought that mine from Ingelson's was perfect, but I did not think yours was good. I have just received half a dozen from Lathrop's and Dunham's of mine. It is the judgment of all that this last is far better than Ingelson's. What do you think? We have a few of the small size of yours, but none yet of mine. {8MR 76.1}
Lathrop is as pleased a man as you ever saw with the pictures, especially of you. He says he will sell you the negative for five hundred dollars. Beside what we take, it will bring him that much custom. He thinks Ingelson's a flat affair. He [Lathrop] has your picture in the window for show.--Letter 1a, 1876, p. 1. (To James White, March 24, 1876.) {8MR 76.2}
In regard to our pictures, how many shall we order? Dunham gave me mine as well as yours--one dozen each. This is liberal, I think. Everyone thinks these last [pictures] from Dunham's are perfect. What is your judgment? Lucinda's are not yet finished. No orders, he says, were left for him, but one dozen will be finished in a short time.--Letter 3, 1876, pp. 3, 4. (To James White, April 4, 1876.) {8MR 76.3}
I have just gotten the picture Dunham has made. I do not like it. Shall not order any till you see it and send your opinion of it.--Letter 12, 1876, p. 1. (To James White, April 21, 1876.) {8MR 76.4}
In regard to my small picture, I did sit once again, but the picture was not good. Will try it again. Mary and Willie did not get good pictures, but they will try it again.--Letter 15, 1876. (To James White, April 27, 1876.) {8MR 77.1}
I do not think I shall ever get a picture to equal the one Dunham has made for me. He says I had better have the large one put on a small card. What do you think of this plan?--Letter 17, 1876, p. 2. (To James White, April 30, 1876.) {8MR 77.2}
Father, I am sure, has confidence in you. We often hear him speak of you and Emma with pleasure in high terms. He shows your pictures and he calls you two his "canaries."--Letter 22, 1879, p. 1. (To Edson White, July 1, 1879.) {8MR 77.4}
If you have Father's pictures, please bring them. I want to show them. My pocket album I left at Healdsburg.--Letter 15, 1882, p. 1. (To W. C. White, May 23, 1882). {8MR 77.5}
Well, Addie [Walling], I would be pleased to have you get your picture taken and write to May [Walling] to do the same. I will settle the bills. I want to see the faces of my children once more.--Letter 101, 1886, p. 4. (To Addie Walling, July 21, 1886.) {8MR 79.2}
