Although Williams has not carried forward on appeal his objection that the photographs were irrelevant, we note in passing that they were relevant to aid the jury in visualizing testimony regarding the nature of the medical treatment which was administered to the children in the pediatric intensive care unit and the sequence of events leading up to their deaths. It is the trial court's function to decide in the exercise of its discretion whether or not a photograph is a fair and accurate representation of the scene sought to be depicted, City Council of Augusta v. Lee, 153 Ga. App. 94 (4) ( 264 S.E.2d 683) (1980), and unless manifestly abused the exercise of that discretion will not be controlled by this court, Collins v. State, 248 Ga. 687 (2) ( 286 S.E.2d 8) (1982). In this case the two photographs were offered to depict the setting in which the children had been hospitalized.

In many cases where we have upheld charges to the jury against attacks based on Sandstrom, it appears that the juries were instructed that criminal intent is never presumed, that the burden of proving intent rests on the State, or that intent is always an issue for the jury.

Since this is a court for correction of errors of law, our decision must be made upon the record and not upon briefs of counsel. Belluso v. Sunnyland Foods, 142 Ga. App. 7 (1) ( 234 S.E.2d 821) (1977); Collins v. State, 248 Ga. 687, 689 (2) ( 286 S.E.2d 8) (1982). See Smith v. Goerlich's, 112 Ga. App. 374, 376 (2) ( 145 S.E.2d 385) (1965).
